The interior problem is most likely a result of a bad vacuum hose. The vents are actuated by engine vacuum. Chances are one of the vacuum hoses under the dash is either broken, disconnected, or cracked. As a result, the vent isn't allowing heat to make it to its destination.

Check for leaks. With the engine running, you may hear a hissing sound.

Let me know what you find.
